ref: sample lab and INE atc video.
I can see in sample lab tranport mode ethernet/vlan command is missing.
But in INE atc video's i can see transport mode ethernet .
What is the difference ?
By Default Cisco routers negotiate and establish VC type 5 (Ethernet type transport) circuits between them. Actually for EoMPLS or VPLS two VC types exist, VC type 4 (VLAN mode) and VC type 5 (Port Mode). The difference between VC 4 and VC 5 is that in VC 5 the VLAN tag is not transferred (it is removed and not trasnmitted)over MPLS. Bandiwtdh is saved in that way.
Read this post:
what i understand is
transport-mode ethernet is by default .
VPLS speaking and supported Cisco platforms yes, default is VC type 5.
What is VLAN over VPLS.
